pg-dev is a package for Atom editor, in order to help developing on PostgreSQL (functions).
Load functions from file system, so you MUST have the functions mapped there.
Set main directory path: must be an absolute path on package config.
Set workspace directories (support multiples, splitted by comma) on package config. By default, the functions must go inside of "functions" directory (The package must read this files as functions).
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
